I see three card options: pcie, pci, integrated. PCI was selected. I switched it to PCI-E.
I can only choose one option. Ok, then, how would the system enable both? The ati driver can be added to the Linux installment and the ati/radeon driver I had enabled prior to buying the graphics card.
I'm going to have to look back at the given post because I don't see how it's done.
